Be it known Athat I, BENJAMIN WV.

Toonen, a citizen of the United States, anda fresidentof South Orange, county of Essex,

and. State of NewA Jersey, have invented certain new and useful Improvements in Type- .'Vi'iting lvlachines, ot which the following is a full, clear, and exact description.

This invention relates more particularly to the carriages of typewriting machines in" which worksheets wider than the carriage may be written jupon.

One of' the principal objects of the inventionis to provide a carriage for a writing machine, inwhich a platen may be mounted and which is so constructed that work sheets. as wide paper, long envelops, and thelike 'i .may be placed about the platen and the work sheet handled in as ready a manner as in thc ordinary machine, without making @the carriage extensible and without in any way interfering with the proper working of the parts of the carriage or the parts usually associated therewith.

- Another object ofthe invention is to pro yide a simple and efiicient carriage in which -the pla-ten may be supported at its ends and the work sheet so held about the platen that the -platen may be independently rotated or moved for line spacing, notwithstanding the fact that the Work sheet may extend on either or both sides lbeyond the ends of the platen;

Other objects of the invention are to provide simple Vand efficient means whereby the work sheet may be released in order that it may be readily adjusted about the platen; to

lrovide sim ie means for su ortinO the work sheetwhile beingwritten upon; to pr0- vvide simple means whereby. the work sheet may be released; and to provide simple and eiiicient line-spacing means for the platen. y

A further object of the invention is .to provide a simple andw eiiicient carriage adapted for visible writing, which may be readily made and assembled, and in which the parts need not necessarily occupy much more space than the ordinary carriage.

yA istill fin-,ther object of the invention is to provide a carriage which is particularly adapted for small portable personal writing machine; of v:;"ious kinds.

With these and other objects in View, the

larly described with reference to the accompanying drawings, which lform a part of this application, and will then be pointed out in the claims at the end ot' the description.

In the drawings, Figure l is a front eleva tion of one form of carriage embodying the invention.

Fig. 2 is an end elevation of the vcarriage looking from the left hand side of. the machine.

Fig. 3 is an end elevation looking from the right hand side of the machine.

Fig. i is a view similar to Fig. 3, except that the feed roll and certain other` parts have been moved to a position to release the work sheet about the platen. A

Fig. l9`is a plan View of stiliannther foi-m of platen `carriage.

.. sheets of the usual or of widths wider than the carriage to 'be written upon, it will be understood that many of the tea-tures shown may be. employed in connection with carriages or writing machines of various kinds and constructions.

The carriage bed 1G may be supported in any desired way and mounted. to travel lengthwise ot' the bed under the force of a spring drum or other motor is a carriage 11. As shown the carriage provided with rollers 12 along one edge thereof, and ball bearings llalong the other edge so as to adapt the carriage to more readily alongl its bed. The carriage is also adapted to be controlled by suitable esiapement mechanism, but such mechanism as well as the mounting* of the carriage may be ot'jany suitable construction.

y The carriage frame 1J has end pieces, brackets or iframe memo 's 1:3 which. may be joined together by a member or work sheet receiver .1.6. The member 1G may be of open work, as wire, or thin plate, either solid .or provided with openings to lighten the same, and ir" made ot metal, as .i'luminum,

will add comparatively little weight to the carriage. lhe end members or bracket-s 15 ane substantially annular in form, having an opening, throat, or channel 1?. The member 16 is substantially cylindrical in torni, and isarranged to conform to Vthe shape of the Opening 18 of the end pieces 15. The ends of the cylindrical member 16 are not joined together Ibut provide a throat or opening correspondingT to the cham'iel 17 in order that the work sheet, may be caused to pass through the opening 18 into and from the cylinder 16, as will be presently described.v One end of the member 1G is fas tened to the end brackets 15 by screws or otherwise and the other end of the cylindrical member 16 may be provided with upturned parts or lugs 20, by which said end may be secured br screws 21 or otherwise to the outer surface of said brackets 15. The end brackets 15 are extended forward to provide lugs and mounted ip said lugs to' Ileng'th. extends back ot the platen and pressure or feed roll 24, and ascends through the throat 17 into the opening 1S, formed by the cylinder or body 16 wherein it may be rolled upon itself to occupy as little space as possible, and from which Condition the said work sheet is fed forward between the feed roll and platen upwardly above the platen as is usual in visible writing machines.

The pressure or feed roll 24 is held to rotate in a carriage frame member This frame member is hinged at QG to the for ward ends .27 ot the carriage end brackets 15. 'A rod Q8 extends lengthwise of the carriage between the end frame brackets 15 forming a hinged connection between the part and said end brackets. A transversely extending bar 29 is held at. its ends between the end bracket-s 15 and a bar Si() extends between the ends of the carriage frame member for the pressure roll. The

two bars 29 and 30 are arranged in parallel relation and have lugs 31 extending out- *ardly therefrom so as to provide bearings for the rod 28. At one or both ends ot' the rod 2S is arranged a spring 3'2 one end ot which Spring is held under the the other end under the bar 30, the tension oi the spring or springs tending to force the irame 25 with the pressure roll 'il against the platen so that under normal conditions the platen and pressure roll will rotate in unison. The carriage frame part has a plate 33 on its upper surface which forms substantially a Continuation of the forward odge of the member 16, and said plate with the'plate like cylindrical member 16 pio vides a proper surface for guidiuef the 'work sheet backward-ly or forwardly l ,tween the platen and pressure roll without offering' any obstruction thereto whatever. 'ilhe plate 33 1s cut away to permit the roll 2st to ex tend through the sayne,and saidk roll .21 is also cut away to provide space-ul members or parts 34 between which parts a part of the plate 33 extends in order that a substantially continuous table may be provided tor the work sheet. .A handle 35 may be arranged. at either or both sides of the machine on the pressure roll frame 25 to adapt said frame -to be moved on its hinge 2G to release the pressure roll from' the platen to adapt the work sheet to be adjusted. By this means the work sheets may be properly held and fed between the platen Q8 and the pressure roll 24, either into the body or receiver 1u or forwardly for printing purposes, as desired. l

A knol) 3G is mounted to rotate upon a stud 37.w rlhis stud 37 is held to one ot' the carriage end brackets aud may be located adjacent to the handle 35. 'lhe knob $3?? may be llcld to a sleeve 2lb, and on the inner und of said sleeve is a pinion 'll which meshes with another pinion J0, The pinion 40 is held to the axis 41 of the pressure roll so that by rotating the knob the pressure roll )ar 29 and ing the work sheet.

As a. means for line-spacing 'the platen provide a ratchet wheel 42 which is engaged may be rotated in either direction for feedby a lever-actuated -pawl 43. The paw-l 43 is mounted upon a manually operable lever 44. This lever is pivot-ed to swing about the shaft or stud 45, and during its swinging movement causes the pawl to move the ratchet wheel 42 according to the dist'aiice the lever 411- is moved, there being a spring 46 tending normally to force the pawl 43 into engagement with the teeth ot" said ratchet wheel. The shaft or stud 45 is mounted on one of the carriage end brackets at substantially a right angle to the axis of the pressure roll, and ou` the inner end of said shaft 45 isa. bevel gear or pinion 47 which meshes with a smaller gear or pinion 2o 48 on the axis of the pressure roll, so that when the ratchet wheel 42 is rotated a. rotary movement is imparted to said pressure roll. The lever 44 moves in a direction lengthwise of the carriage, and may serve as a means for moving the carriage backward against its letter-spacing movement and with such backward movement simultaneously line-space the platen. 44 has a downwardly projecting part 49 to 3 0 which is held one end of a spring 50, said spring at its other end being secured to a fixed part of the carriage frame. The part 49 of the lever 44 is adapted toengage a stop 51. This stop is for the purpose of limiting the extent of movement of the lever '44 so that the platen may bezmoved a single 0r double space or otherwise, according to the position of said stop 51. This stop-51 is rotatably held on a stud 52. The stop 51 40 comprises a block portion or part 53, and

' formed integral with the block portion is a knurled head 54 by which the stop may ent vadjusted-positions by means of a spring 56,-one end of which is held to a fixed part of the-carriage and the other end of which is free and is adapted to engage onerof the sides of the block 53 to frictionally hold the same in any one of its adjusted positions. The block 53 is cut away to provide an engaging portion 57 on one side thereof,

55 and is cut away at 58 ttprovide another engaging portion. The'engagiiig portions 5l. and 58 are of relatively different distances from the axis of the stop and as such engaging portions of the stop are the parts M engaged by the projecting endA 49 of the .line spacing lever 44 the extent of movement of saidv line-spacing lever is determined by said'portions. When the stop is adjusted so that the lever end 49 will engage the plane side oi" front of the block 53 a single The lever line-space movement may be imparted to the platen, and when the stop isadjusted so that the lever will engage the part 57 two linev spaces may be given to the platen at a single movement ofthe lever 44. and if the stop is `adjusted so that the lever end 49 engages the cut away pait 5S the platen may be given three line-space movements. The line-spacing lever 44 may have its backward movement limited by a` suitable stop 58u. Un the-end bracket. or al part projecting therefrom adjacent to the ratchet wheel 42 may be an enlarged cani portion 59 which is adapted to be engaged by the paw] 43 during its backward movement so as to release the pawl from engagement with the teeth of the ratchet wheel, when the lever 44 is in its normal.v position. A toothed wheel 60 is'secured to the shaft of the pressure roll and this toothed wheel is adapted to be engaged by a roll 61. The. roll 61 is carried upon an arm 62 and this arm is 1iormally forced toward the toothed wheel 60 by a spring G3 and tends normally -to hold the pressure roll in any one of its linespacing movements and permits the `said pressure roll to be moved in either direction.

The carriage may he provided with paper fingers 64 which are adjustably held to a bar 65 carried by the pressure roll frame 25. These fingers maybe adjusted lengthwise of the platen and at Vthe upper end thereof A may have rolls 66 mountedwthereon as is usual. The pressure roll, frame 25 may be provided witlra. scale 67 at the foi-'Ward edge thereof, and there /nia'j be also provided type-lining means, las 65,'which-may be hinged to adapt the saine to be moved with the pressure roll awayv fromtliegplaten.

In Figs. 13 to 16 a construction is shown wherein the line-spacing mechanism is ranged upon the axis of the platen itself instead of the pressure roll, and means' is also provided whereby the platen may be v Adirectly operated independent of the linespacing mechanism.. As shown the carriage 69' is constructed, except so far as the linespacing means and the means for rotating the platen is concerned, substantially the saine as already described. The pressure roll 'OiSJnounted upon a movable trame so as to be 'released from the platen 71 and the form of the' carriage frame withv the cylindrical receiver and the elongated throat for the Work sheet is the same as that shown in Figs. 1 to 4. The plateirl may have the usual rml member with the impact cylindrical cove/ruig of rubber or other material and at one end thereof may have a bushing 72 and at` the other end may have a bushing 73.

The bushing 72 has azsteiii or? stud portion 74 projecting oiitwardl y "from one side thereof, and this stem has a reduced part onterng ai -fnei iti-g 'n ouf ci' the carriage end brackets to rotatably support the platen at (gne end in the carriage frame. The bushing 13 1s provided with a central opening therethrough and extending through the opening is a shaft or rod T5. The rod extends through an opening in the carriage end -frame adjacent to the bushing T3 some distance into the platen and at one end is provided with a knob or button 76. At the opposite end of the rod 75 within the platen is a key 77 which is adapted to engage a slot or key-way in a collar 7S forming a part of the platen` rlhe key 77 permits the extension of the rod T5 so that said rodmay be made to rotate the platen whether the knob 70 is close to the end'bracket of the' earriapre or at a distance therefrom. This permits the platen to be rotated manually at ivill in either direction independent of the line-spacing; mechanism in case-the Work sheet is wider than'the carriage is lonfr. The rod Tinay be groovod at intervals as at 79, and adapted to engage said grooves is a latch 80. The latch S0 is pivoted at S1 to the carriage' frame and is normally forced in one direction by a spring S2. The latch is provided with an openingr 83 through which therod T5 passes and said opening' provides an engaging' part S-l to enter the 2( {roove to prevent the rod from being extended or forced into the platen and to hold the saine in its adjusted position Whatever it may be until the latch is released. The latch 80 is substantially bell-crank in form and on one arm thereof is provided with a ingerkey or part 85 by which the latch may be depressed as shown in4 Fig. 17 to release the saine from engagement with any one of the grooves 79 and thereby permit adjustment of the rod 75.

As line-spacing means for the construction shown in Fig-s'. 13 to 16 the stem T-l of the bushing 72 is provided with a ratchet Wheel 86. rlhis ratchet Wheel 86 is adapted to be engaged by a pawl S7 which is pivotally held to a lever S8 and is norinall pressed by a spring 89 into engagement Wit the teeth ot the ratchet wheel. The level 88 is pivotally held to the stem 74. andis connected by a link 90 to a lever 91. 4The lever 91 isvpivoted at 92 to one of the carriage brackets and has a finger portion 93 located at the rear of the carriage. The lever' 91 is sickle-like in forni, having` the main body port-ionv thereof grooved to the shape of the cylindrical body of the carriage so as not to interfere with the work sheet when' extendingl within the carriage as already explained. The lever 03 and pawl carrying lever 88 may be restored to a normal position by a spring or otherwise, and the cxtcnt of movement of the lever SS may be limited by a manually movable stop 0l in substantially the same manner as the linespaciug action of the panl is controlled in the Corona typewriter. The platen may also be held in its varioussuggested positions by a friction roll as 95, which is supported at the end of a spring held lever 00 and which serves to hold the platen andl still permit it to rotate in either direction.

Figs. 10 to Q1 shew a construction Where in the platen itself may be raised to releasf;r the ivork sheet for adjustinentpr other pur4 poses. nthis forni the carriage Sl'has a cylindrical body 98 with a throat 99 for thr passage of the Work sheet, as already de scribed, and has a forwardly extendingr parl 100 in which is rotatably held a pressnir roll'101. The pressure roll 101 is. adaptei to be rotated by a knob'102 and instead ol' being); pressed against the platen as in the other forni the platen 103 is pressed normally against the roll 101. As shown,l the platen 103 is mounted to rotate in arms at each end of the carriage, only one of said arms beiner shown. The arms 101i are pivoted at 105 to the forward part of the carriag'e frame adjacent to the throat 99 and -said arms and platen are normally forced toward the roll 101 by springs 106. The springs 106 may be arranged around a rod 107 having o ne end thereof engaging` the arms 101i and the other end engaging' under a tixed part of the carriage teinlingi normally to force the platen downwardly, .A handle 108 may be arranged on one or both arms to adapt the platen to be raised to release the work sheet, as shown in Fig. 21. Except as described, the parts shown are snbstan- I tially the saneas that shown in the other figures.

It will be evident from the foregoing that -a carriage construction is provided whereby wide or long Work sheets may be employed and written upon which are wider'than the length of the carriage or the platen; that simple nieans are provided swhereby 'fthe Work sheetis properly held between pressure means and the platen; that the construction is such that the'carriage is adapted for front strike or other Writing means; and

that simple and etlicient means is provided whereby thew'ork sheet may be readily adjusted and line spaced.
